Railfreight Construction/Trainload Construction. One each F4404 & F4320 - 1000mm (prototype size) Symbols and standard TOPS numbers in black. Enough for two engines. The 1000mm (prototype size) symbols on sheets F4400-F4409 are authentic for loco classes 26, 31, 33, 47, 56, 86. 1200mm (prototype) sizes, see sheets F4410-F4420. For information only - there were no Class 20s included in at least the original specifications for Railfreight Sector Livery. Some Class 20s were indeed painted in the triple grey paint scheme, but only carried the black TOPS numbering. The reasoning behind this 'anonymous' appearance being that the class was not entirely suited to the new dedicated Railfreight Sector operations, their lack of power/driving cabs at one end only necessitating their working in nose-to-nose pairs. In addition, the number of inspection doors in the body would have caused issues in decal application. If indeed any of the class did have the markings applied, then they would likely be the smaller - 1000mm - version. I do not recall seeing any images of 20s in full livery.
